Semiconductor quantum computation [PDF]
National Science Review, 2018 AbstractSemiconductors, a significant type of material in the information era, are becoming more and more powerful in the field of quantum information. In recent decades, semiconductor quantum computation was investigated thoroughly across the world and developed with a dramatically fast speed.

Holographic Quantum Computing [PDF]
Physical Review Letters, 2008 We propose that a single mesoscopic ensemble of trapped polar molecules can support a "holographic quantum computer" with hundreds of qubits encoded in collective excitations with definite spatial phase variations. Each phase pattern is uniquely addressed by optical Raman processes with classical optical fields, while one- and two-qubit gates are ...

BLIND QUANTUM COMPUTATION [PDF]
International Journal of Quantum Information, 2006 We investigate the possibility of having someone carry out the work of executing a function for you, but without letting him learn anything about your input. Say Alice wants Bob to compute some known function f upon her input x, but wants to prevent Bob from learning anything about x.

A (quasi-)polynomial time heuristic algorithm for synthesizing T-depth optimal circuits
npj Quantum Information, 2022 We investigate the problem of synthesizing T-depth optimal quantum circuits for exactly implementable unitaries over the Clifford+T gate set. We construct a subset, $${{\mathbb{V}}}_{n}$$ V n , of T-depth 1 unitaries.

Quantum computing with four-particle decoherence-free states in ion trap [PDF]
, 2001 Quantum computing gates are proposed to apply on trapped ions in decoherence-free states. As phase changes due to time evolution of components with different eigenenergies of quantum superposition are completely frozen, quantum computing based on this ...

Quantum picturalism for topological cluster-state computing
, 2020 Topological quantum computing is a way of allowing precise quantum computations to run on noisy and imperfect hardware. One implementation uses surface codes created by forming defects in a highly-entangled cluster state.

IEEE Transactions on Quantum Engineering, 2020 Control electronics for superconducting quantum processors have strict requirements for accurate command of the sensitive quantum states of their qubits. Hinging on the purity of ultra-phase-stable oscillators to upconvert very-low-noise baseband pulses,

T-count and T-depth of any multi-qubit unitary
npj Quantum Information, 2022 We design an algorithm to determine the (minimum) T-count of any n-qubit (n ≥ 1) unitary W of size 2 n × 2 n , over the Clifford+T gate set. The space and time complexity of our algorithm are $$O\left({2}^{2n}\right)$$ O 2 2 n and $$O\left({2}^{2n ...
